White Knight Pump Decontamination Instructions
White Knight pumps are designed to pump caustic and otherwise dangerous liquids. Therefore, every pump must be handled as if it contains dangerous chemicals whether or not it actually does. White Knight specifies that if a pump runs under it’s own power that the pump should circulate DI water for twenty minutes before disassembly or double bagging for shipment. If the pump does not run under it’s own power, then DI water should be forced from the inlet, through the outlet for 40 minutes before disassembly or double bagging for shipment. Only those who have been adequately trained in safety with and the handling of acids and other dangerous chemicals should attempt to handle a White Knight pump that has been used. Adequate safety gear appropriate for the chemical that has been in the pump must be used/worn and no attempt should be made to handle the pump until Material Safety Data Sheets (here after MSDS) for the chemical that the pump has been used in have been reviewed. Ph Papers, Showers, antidotes, clean-up equipment, neutralizers, and any other safety devices that could be used for detecting, neutralizing or minimizing effects from the chemical described in the appropriate MSDS must be present as well as emergency numbers for use in the event of an accident. Take great care in the handling of liquids and/or residues contained in these pumps or any other chemical handling equipment. Remember, Safety First.
Any pumps returned to White Knight for warranty evaluation or repair must be complete with all parts and components including but not limited to base plates, mount screws, tubing connectors, tubing connector caps, flare noses, shuttle valves, mufflers, and tubing. Any missing parts will be added to the pump and charged to the customer in the event of repair or replacement, warranty or otherwise.
Removal of Pump From Station:
- Disconnect liquid tubing connectors from the front (opposite the externally mounted shuttle valve) of the pump.
- Plug npt fittings with PTFE plug, Flare fittings with flare nose cover and cap, or other plug or cap as recommended by connector supplier.
- Disconnect air supply tubing from face of shuttle valve.
- Loosen mount screw (#20) from Base Plate (#18) using thumb and forefinger but do not completely remove the screw from the base plate.
- If another White Knight pump of the same model number is to go into the same application the base plates are interchangeable and the base plate in the station would not need to be removed. Otherwise, the base plate should be removed using the proper tool for the fastening devices (not provided by White Knight) used. (usually allen wrenches or flat head screw driver).
- Return all removed parts to the pump.
Return of Pump to White Knight:
- After removing the pump from the station the pump must be flushed as described in the attention section of this document.
- Remaining DI water in the pump should be drained from the inlet and outlet liquid tubing connectors to the greatest extent possible.
- The pump liquid outlets must then be plugged as described in the removal of pump from station section of this document on line two.
- Dry off the pump.
- Double bag the pump sealing it in thick polyethylene bags.
- Return the pump to its original packaging.
- Include MSDS for the chemical that the pump was handling in the box with the pump.
- Obtain RMA number from White Knight and write it on the outside of the box.
